I recently added a wireless AP to my network. This means I now want firewalls on all my boxen. Which ports do I have to have open so I can export NFS?
I found:
sunrpc 111/tcp portmapper # RPC 4.0 portmapper TCP sunrpc 111/udp portmapper # RPC 4.0 portmapper UDP nfs 2049/tcp nfsd nfs 2049/udp nfsd
What else?
Those should be fine for normal use, but you can also look at other open ports via `rpcinfo -p`.
Also be aware of security. NFS has only host/IP based security. Meaning anyone driving by that can hop on your WAP, choose an IP address and mount your exports. and may do nasty things.
